Description: Viterbi decoding of convolutional code with half rate & four state. It can done by two matrics . that is branch metrics and path metrics. Branch metrics is hamming distance between the parity bits and received bits. If branch metrics is zero then no error. Otherwise bit error occurred.path metrics is the hamming distance of path initial state to current state.the path with smallest distance result in less number of bit errors.-Viterbi decoding of convolutional code with half rate & four state.

Description: this code is the hamming windowind(In signal processing, a window function (also known as an apodization function or tapering function[1]) is a mathematical function that is zero-valued outside of some chosen interval. For instance, a function that is constant inside the interval and zero elsewhere is called a rectangular window, which describes the shape of its graphical representation. When another function or waveform/data-sequence is multiplied by a window function, the product is also zero-valued outside the interval: all that is left is the part where they overlap, the "view through the window")
